As we can see it already has the making of the Stahlhelms that we know and love.
The distinctive curves and rolled edge found on the M35 and M40 pattern helmets.
Throughout the First World War the helmet design changed to create the M17 and M18, the number denoting its year of introduction.
The M18 had ear cut outs to allow for easier hearing and also can be seen being used by telephone and radio operators.
During the inter war years the German government modified the helmet again however they were very
restricted by the Versailles treaty. This was an effort to
improve the look and usability of the helmet. However due to these restrictions the M17 was reproduced to meet the need.
As we all know the National Socialists came to power in 1933 and threw out the Versailles treaty and began designing and producing their own helmets and in 1935 a new helmet was approved by the armed forces and this became known as the M35.
